Hi! i'm a first time poster and new to the MMA world. I'd like to start training in bjj, or Judo to get in better shape and learn technique etc.. Unfortunatly i'm a little to strapped with cash until the new year to take any adult classes. Is it possible to learn using books/ instructional dvds? I have no other experience in MMA and dont wish to pick up bad habits. Would it be better for a guy like me to wait until i can take actual classes? Thanks.
